The theories of flight safety are examined from the thinking pattern point of view. Due to the different evolving environments of western and Chinese cultures, the basic thinking patterns are fundamentally different. The western linear thinking, based on the “event” of flight operation, results in the causal sequential type of flight safety theories such as the domino, accident chain, cheese theories. The Chinese pictographic thinking forms the different theory like the Flight Safety Margin based on the “feature” of flight situation, although which can only represent a very preliminary trial. The flight situation composed of features with many interacting factors included is used to comprehend the accident by the Chinese. How the features are extracted from flight operation still needs to be studied scientifically. How the features are correlated to form the significance of safety is another difficult problem. To clarify the Chinese thinking patterns in aviation safety will be a valuable research field especially after the Chinese C-919.
